SPK MoSi₂ heating element

1. MoSi2 heating elements should not be used within the temperature range of 400 ℃ to 700 ℃. Therefore, under such adverse conditions, the elements will be oxidized at low temperature and cause damage to the elements.

2. MoSi2 heating elements are suitable for use in air and neutral atmosphere, reducing atmosphere such as hydrogen will damage the protective layer, and chlorine and sulfur vapor will directly damage the elements.

3. MoSi2 heating elements soften at high temperature (above 1500 ℃), and are hard and brittle at low temperature. In order to avoid stress during temperature change and facilitate the expansion and contraction of elements, it is better to use free vertical hanging installation method. The removal and replacement of lifting elements is also more convenient, and can be heat exchanged without waiting for the furnace to cool down.
